81 mm
The outer boundary of a body or figure.
the area is 18
it is the area of a solid object times by the square root of the perimiter
Multiply one of the sides by 4.
area is inside and and perimeter is outline.
base times height minus half of the perimiter base times height minus half of the perimiter
perimiter
just the area around the outside of it so think of the perimiter and add the area so just measure the area and perimiter and add them 2gether
the continuous line forming the boundary of a closed geometric figure
to find the perimiter you just add up all the sides....Perimiter is the same for every figure.
